Knowing that the carbon 14 has a half life of 5,730 years allows the estimation of the age of the object based on the fraction of carbon 14 remaining.

Uranium-lead dating is an established radiometric dating technique.

Any technique which dates a material based on the known decay rate of a radioactive component of the material is a form of radiometric dating.

There are many radioactive elements and thus many applications of the basic principle.

Anything which changes the relative amounts of the two isotopes (original and daughter) must be noted, and avoided if possible.

By this method, the age of the Earth has been estimated to be about 4.6 billion years.Example sentence: One of the early tests of radiometric dating was to estimate the age of the wood from an ancient Egyptian artifact, for which the age was already known from historical documents.
